IMPORTANT NOTE

The requirements below apply to those students with a 2024-2025 catalog year. Students are required by college policy to follow the major (and minor) requirements found in the catalog in effect at the time they declared their first major. To find your catalog year, please visit your Grades and Academic Records found in myOxy and access the catalog that matches your catalog year.

There are three focus areas in the major: the standard Computer Science focus, the Computational Math focus for students who have a more theoretical interest, and the CS+X focus for students who want to dive into the intersections between computing and other disciplines in the liberal arts (forming the discipline X).

All 100-level COMP courses are appropriate for students with no computer science experience. For students exploring their interest in the major, we recommend starting with COMP 131, which will provide an introduction that should determine their levels of interest and enjoyment in the subject. Students with previous experience that includes object-oriented programming may be able to start at a more advanced level (see Placement Information below). Once students have completed COMP 131, they should enroll in COMP 229 (Data Structures), which serves as a gateway course to upper-division courses. Students may also take COMP 239 (Computer Organization). Both courses are required for the major. Students are also encouraged to take COMP 101 (Justice and Equity in Technology) as early as possible.

The CS department typically offers 4-5 upper-division electives each semester. Note that our required upper-level seminars, COMP 390 (Junior Seminar) and COMP 490 (Senior Seminar), are only offered in the Spring and the Fall semesters respectively, and should be taken in the Junior Spring semester and the Senior Spring semester. Careful schedule planning is recommended for majors, and students who wish to study abroad should talk to their advisor as early as possible.

Placement Information

Students interested in the Computer Science major who have not previously studied object-oriented programming do not need to take a placement exam and should start with COMP 131.

Students who received a 4 or 5 on the AP Computer Science exam do not need to take COMP 131 and should start the major by taking COMP 229. Students who are uncertain of their programming abilities may elect to take COMP 181 (Advanced Programming), which is not required for the major but is designed to refresh/strengthen students’ programming abilities.

Other students who have previously studied programming have the option of taking the CS Self-Placement Exercise.

Computer Science Transfer Student Advice

Transfer Course Limit for Transfer Students: No Limit

Designated Transfer Adviser


Expected preparation for transfer students wanting to major in Computer Science:

  • Junior transfer students must have completed a course equivalent to COMP 131 and preferably also COMP 229. Students who have not completed a course equivalent to COMP 229 may still be able to complete the program in two years, but the sequencing will be more difficult. The majority of Core requirements should have been completed. Junior transfer students starting in the spring semester should also have completed at least one upper-level Computer Science elective prior to transferring to Occidental.

  • Transfer students starting mid way through their sophomore year should have completed the equivalent of COMP 131.


What courses should a transfer student take during their first semester at Occidental?

  • Junior transfers should take COMP 101, COMP 229 (if they have not previously taken a data structures course), and a Computer Science elective numbered 240 or above. 

  • Transfer students starting mid way through their sophomore year should take COMP 229 and COMP 101

  • Sophomore transfer students should take COMP 131 if they have not already taken an equivalent course.
